JOURNAL-BEARING'.

Specification of Letters Patent.

Application Iled January 30, 1911.

Patented Oct. 24, 1911.

Serial No. 605,440.

To all whom it may concern.'

Be it known thatI,JoHN S'rURRocK, asubject of the King of Great Britain,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Journal-Bearings, ofwhich the following is a specification.

My invention relates to grain drills, and in particular to theconstruction of the bearing for the rotatable disk furrow opener, itsobject being to provide a bearing that may be economically manufactured,strong in its construction, comparatively dust proof, and durable in itsoperation. I attain these objects by means 0f the mechanism illustratedin the accompanying drawings, in which- Figure 1 represents a sideelevat-ion of a disk furrow opener having my invention forming a partthereof; Fig. 2 is a rear elevation of Fig. 1; Fig. 3 is a verticalsection of Fig. 1 through the axis of the disk; Fig. 4: is a sideelevation of a bearing supportdetached from the drag bar; Fig. 5represents an end elevation o-f a bearing block; Fig. 6 is a verticalsection of Fig. 5 illustrating the manner of connecting the bearingblock with its supporting member; and Fig. 7 represents a rear view ofFig. 5.

The same reference characters designate like parts throughout theseveral views.

1 represents a drag bar that may be connected with the frame of themachine in any desired manner.

2 is the bearing block support mounted upon the rear end of the dragbar, having integral therewith a vertically extending oil tube 3 and anaxial opening surrounded by a boss 4, having radially arranged ribs 5thereon.

6 represents a bearing block having a reduced inwardly extending bossportion 7 provided with a counterbored portion 8 adapted to receive theboss 4, and radially arranged cavities 9 at the bottom of thecounterbored portion adapted to receive the ribs 5.

10 represents a circular flange at the outer end of the bearing blockthat is inclosed by a cup-shaped casing 11 and a circular plate 12secured to the disk 13 by means of bolts 14: passing through the platenear its periphery and through an annular flange 15 forming part of thecasing. The block is provided with an axially arranged pocket 16 at itsouter end that is adapted to receive the head of a bolt 17 that securesthe block and its support to the drag bar, the pocket being adapted toreceive a supply of lubricant.

18 represents an annular channel upon the inner face of the circularflange 10, that is adapted to receive a dust excluding washer 19 thatengages with t-he interior surface of the casing and with the reducedportion of the bearing block.

2O represent-s radially arranged lubricant channels upon the outersurface of the bearing block, having their inner ends communicating withlongitudinally arranged channels 21 extending through the axial openingin the reduced portion of the block and communicating with the oil tube3, and 22 represents concentrically arranged openings leading from theouter face of the block and the pocket therein to the bottom of theannular channel 1S. The outer end of the oil tube 3 is provided with acommon form of pressure grease cup, and the ducts, channels and pocketare kept completely filled with lubricant, and pressure applied upon thelubricant contained in the cup is transmitted to that portion occupyingthe openings 22, and against the inner face of the dust excluding washerin a manner to press it against the surface of the cup-shaped casing.

What I claim as my invention, and desire to secure by Letters Patent,is:

1. A journal bearing including, in combination, a rotatable element, asupporting element, a bearing block secured to said supporting elementagainst rotation, said block having a reduced boss portion of its innerend and an enlarged circular flange at its outer end, a cup-shapedcasing inclosing said flange and secured to said rotatable element, aplate secured to said rotatable element and engaging with the outersurface of said flange, the inner surface of said flange being providedwith an annular channel adapted to receive a dust excluding washer, alubricant pocket at the outer end of said bearing and means forsupplying lubricant thereto under pressure, and a series of openingscommunicating directly with said pocket and with the bottom of saidchannel.

2. A journal bearing including, in combination, a rotatable element, asupporting element, a bearing support secured to said supportingelement, a bearing block secured to said support, said bearing blockhaving a reduced boss portion at its inner end and an enlarged circularflange at its outer end, a cup-shaped casing secured to said rotatableelement and inclosing the periphery and the inner surface of saidiiange, a plate secured to said rotatable element and engaging the outersurface of said flange, said flange having an annular channel upon itsinner surface surrounding the reduced portion of said bearing block, adust excluding Washer received by said channel, a pressure lubricant cupcarried by said bearing block support, said bearing block provided Withan axially arranged lubricant pocket at its outer end, a series ofopenings coinniunieating directly with said pocket and With the bottomof said annular channel, and lubricant ducts communicating Wit-h saidpressure cup and said pocket.
